Coal beds are one of the most promising reservoirs for geologic carbon dioxide (CO₂) sequestration, as CO₂ can strongly adsorb onto organic matter and displace methane; however, little is known about the long-term fate of CO₂ sequestered in coal beds. The "2800' sand" of the Olla oil field is a coal-bearing, oil and gas-producing reservoir of the Paleocene–Eocene Wilcox Group in north-central Louisiana. In the 1980s, this field, specifically the 2800' sand, was flooded with CO₂ in an enhanced oi...

Upon exposure to anoxia, encysted embryos of the brine shrimp, <i>Artemia franciscana</i>, enter a severely depressed metabolic state, the transition into which is facilitated in part by one of the largest intracellular acidifications ever reported for a eukaryotic organism. However, the endogenous origin of this pH shift remains largely unexplained. We hypothesize that the unexplained acidification is produced by a net flux of protons into the cytoplasm from compartments acidified by a V-type p...

Fluid-saturated experiments were conducted to investigate the elemental partitioning of boron among melt, aqueous vapor and aqueous liquid (brine) in the system haplogranite-H2O-NaCl at 800°C and 100 MPa. Time series experiments demonstrate that equilibrium was reached in about 90 hours. Runs conducted with low-salinity fluids (0--2 wt. % NaCl) show that boron partitions preferentially into the vapor phase over the haplogranitic melt, whereas results from high-salinity (60--80 wt. % NaCI) ...

According to the Department of Water Affairs (DWAF, 2004 p.15), South Africa’s water resources are scarce and extremely limited and much of this precious resource is utilised and consumed in our industries. Treatment and re-use of effluent generated is, in some cases, preferred over use of alternate water resources (Du Plessis, 2008 p.3). The volume of effluent generated in treatment processes like ultra-filtration (UF) and reverse osmosis (RO) units is determined by the feed water quality, with...

To continue running our civilization on fossil fuels while avoiding global warming and ocean acidification, anthropogenic carbon dioxide must be diverted from atmospheric release. For geologic carbon sequestration, the injection of CO 2 into the lithosphere, to operate at the necessary large scale requires an understanding of the multiphase flow properties of high-pressure CO 2 displacing brine in porous media. A laboratory-scale core flooding reactor has been built to measure flow properties ...

Phenotypic plasticity is the ability of an organism to express different phenotypes in response to biotic or abiotic environmental cues. The ability of an organism to make changes during development to adjust to changes in its environment is a key to survival. Sexually reproducing organisms that have short life cycles and that are easy to raise in the laboratory are more conducive for developmental phenotypic plasticity. Considerable research has already been carried out on the brine shrimp, Art...

Carbon capture and storage is one of the technologies that could help reduce CO2 concentration in the atmosphere while contributing to cutback of Greenhouse Gas emissions. Depleted oil and gas fields are favorable targets for CO2 storage because existing wells can be readily used as injection wells. However, a number of abandoned wells also serve as gateway to the reservoir which should be considered in the context of effective Carbon capture and storage. Wellbore cement is a very essential elem...

A novel approach to geologic CO₂ sequestration is the surface dissolution method. This method involves lifting native brine from an aquifer, dissolution of CO₂ into the brine using pressurized mixing and injection of the CO₂ saturated brine back into the aquifer. This approach has several advantages over the conventional approach, including minimization of the risk of buoyancy driven leakage and dramatic reduction in the extent of pressure elevation in the storage structure. The mass transfer co...

The NMR spin-lattice relaxation rate, T(,1)('-1), of water is independent of the Larmor frequency, (omega)/2(pi), in the normal rf range. However, T(,1)('-1) of intracellular water in biological systems, which accounts for as much as 80% of the cell mass, is frequency-dependent. This indicates that the NMR properties of water in the cellular environment are influenced by long-correlation time processes due to the interaction of water with proteins and other macromolecular constituents of the cel...
